FAN ATTACHMENT FOR LAWN-SW INGS.

Patented Jan. 1'9, 1915.

Application filed July 31, 1913. Serial No. 782,327.

To (ZZZ whom it may concern:

Be it known that I, CHARLES F. BETT- MANN, a citizen of the United States, re-

. simple, efficient and inexpensive fan attachment adaptedto be readily applied'to the ordinary lawn swing without necessitating any alteration in the construction thereof, and capable of being operated by the lawn swing to oscillate a fan between .the two swinging seat carrying members of alawn swing in a direction opposite to that of the said seat carrying members, whereby the occupants thereof will be A automatically fanned while operating the swing.

"Y'Vith these and other obj sets in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying draw1ng,and pomtediout in the claims hereto appended; it'beingunderstood that various changes in the form, proportion, size and minor details ofconstruction, within the scope of the claims, maybe resorted to without departing from the spirit or sacriicing any of the advantages of the invention'.

-Like numerals of referencedesignate corresponding parts in all thekfigures of the In the accompanying drawing in which is illustrated the preferred embodiment of theinvention, 11 designat" vertically disposed bearing'arms, constructed of suitable metal and extending upwardly from the crossed side braces 2 of the supporting frame 3 of an ordinary lawn swing and secured to the said braces by the central bolt 4 thereof. The bearing arms 1 are preferably fitted between the crossed braces 2 and they are provided at their lower portions with perforations 5 through which pass the bolts 4, and the lower corners 6 of thebearing' arms are bent in opposite directions to form lugs or projections for engaging the braces 2 at the lower edges thereof, whereby the bearing arms are prevented from turning on the bolts l. Bythis construction, each bearing arm 1 is firmly supported .in an upright positionon a single central bolt and is prevented from swinging downwardly. The bearing arms are provided at their vupper ends with hearing openings 7 for the reception of pivot pins 8 of a transverse pivot bar 9, extending across the swingat the center of the top portion thereof, and provided with a central opening 10 into which is screwed the lower threaded portion 11 of a tube 12, which extends entirely through the pivot bar 9 and projects upwardly and downwardly therefrom. The

tube 12, which constitutes a holder for a rod orstem 13 of a fan holder 14, is firmly secured in the central opening of the pivot bar 9 by upper and lower lock nuts 15 and 16, arranged on the threaded lower portion 11 of the tube 12 and engaging the up er and lower faces of the pivot bar 9. The lower lock nut is provided with a threaded perforation 17 for the reception of a set screw 18. which extends through an opening 19 and engages the rod or stem 13 to enable the fan holder to be raised orlowered and to secure the same in its vertical adjustment. The tube 12 is'arranged in the opening 10 of the pivot bar 9 in proper position so that when the lower lock nut 16 is screwed against the lower face of the pivot barthe threaded perforation 17 of the lock nut will register with the opening 19, which is slightly larger than the perforation. The fan holder comprises the said vertical rod or stem'13 and a lower clamp 20 composed of 'side'plates connected by bolts 21 and provided with tapered upper portions 22, which are riveted or otherwise secured to the lower end of the rod or stem. The side plates of theclamp 20 are resilient and are adapted to clampa'plurality of palm leaf fans 23,

which are preferably arranged as illustrated in Fig. 1 of the drawing, and they constitute an inexpensive and eiiicient fan blade, but any other suitable form of fan blade may, of course, be employed. The bolts 21 are preferably arranged at the ends of the side plates and strips 24 of wood or any other suitable material may be arranged at the inner faces of the side plates 1 for directly engaging the palm leaf fans 23.

The upper projecting portions of the tube 12 constitutes an arm, which is engaged by a clip 25 for attaching the inner end of a connecting rod 26 to the said arm. The clip 25v is preferably constructed of a strip of metal bent atthe. center to form a sleeve for embracing the tubel5 and having extended terminal portions, which are connected by a transverse adjusting bolt 27. The bolt is spaced from the terminals of the projecting portions of the clip, which receives the'rod 26 between such projecting portions. The rod 26, which is constructed of resilient material, is provided at its inner end with an eye 28, which is pivoted between the projecting portions of the inner clip 25 by a bolt 29 or other suitable fastening device. The bolt 27 adjustably clamps the inner clip on the upwardly projecting-portion of the tube 12 and enables the said inner cli-p to be arranged the proper distance from the pivot bar 9- to secure the desired degree of oscillation of the fan. 7

The spring connecting rod 26 has its outer terminal portion 30, connected with the upper crossed rod 31 of one of the oscillatory seat supporting members 32 of the lawn swing. The oscillatory seat supporting member 32 is pivoted above the rod 31 to the supporting frame of the lawn swing by a transverse pivot rod 33 in the usual manner.

. By this arrangement, the outer end of the spring connecting rod is connected: withv the seat supporting member 32' of the lawn swing at a point below thepivot of the said member, and the inner end of the connecting rod is connected to the fan holder above the pivotal point thereof. By connecting theterminals of the rod'26 to opposite sides of the pivotal point of the seat supporting member 32 and the fan holder, the latter is moved in the opposite direction to that of the seat supporting members of the lawn swing, whereby the occupants thereof will be effectively fanned when the seat supporting members are in motion. The outer ter minal portion 30, which'is threaded, pierces projecting portions of an outer clip 3-1, con structed substantially the same as the inner clip and having its sleeve portion embracing the rod 31 of the seat supporting member 32. The projecting portions of the outer clip are connected at an intermediate point by an I adjusting bolt 35, and the threaded terminal portion 30"of the spring connecting rod re ceives a pair of nuts 36 arranged to clamp between them the projecting portions of the outer clip. I I 1 r When the seat supporting member is oscillated, motion is imparted to the projecting upper portion or arm'of the tube 12, and in order to enable the seat supporting member to be swung at a full stroke without injury to the fan attachment even when the parts of the fan attachmentare not exactly proportioned to correspond with the stroke or oscillation of the seat supporting member 32, the spring connecting rod is provided at a point intermediate of its ends with a substantially U-shaped bend 37 composed of spaced sides and a spring coil 38, located at the outer portion of the U-shaped bend and connecting the sides thereof. By this construction, the attachment is adapted to be applied vto various swings without danger of straining or breaking the attachment when the seat members are at a full or complete stroke, as the spring bend will yield 'and permit a longer swing of the seat supporting member than would be possible if at-rigid rod were employed. The nuts 36 and thethreaded terminal portion 30 of the spring connecting rods enable the-latter to be adjusted longitudinally to set the fan attachment approximately inproper position to correspond with the stroke of the seat supporting members.
